Tactile graphic 1970-01-01
Tactile graphics are visual representations designed to be interpreted through touch rather than sight. They are typically used to convey information to individuals who are visually impaired or blind, providing them with a way to access graphical information that would normally be seen. These graphics utilize raised lines, textures, and various materials to represent shapes, patterns, and important details. For example, a tactile graphic of a map might include raised paths and textured areas to represent different terrains, allowing users to explore the layout through touch.
Terra Australis 1970-01-01
Terra Australis, Latin for "Southern Land," is a historical term used to refer to the concept of a vast, uncharted landmass in the southern hemisphere. This notion originated in antiquity, reflecting the belief that there must be a large land area in the southern hemisphere to balance the known lands in the northern hemisphere, particularly Europe, Asia, and Africa.
Terra incognita 1970-01-01
"Terra incognita" is a Latin phrase meaning "unknown land." Historically, it referred to regions that had not yet been mapped or explored, often depicted on ancient and medieval maps as blank spaces or labeled with the term "terra incognita." These areas were often associated with myths or speculations about what might lie within them.
Chess endgame literature 1970-01-01
Chess endgame literature refers to books, articles, and other written resources that focus specifically on the study and understanding of the endgame phase of chess games. The endgame is the final stage of a chess match, characterized by a reduced number of pieces on the board. Mastery of endgames is crucial for players to convert advantages into wins or salvage draws from inferior positions.
Land change modeling 1970-01-01
Land change modeling (LCM) is a set of techniques and methods used to simulate and predict changes in land use and land cover over time. These models assess how different factors—such as human activities, environmental conditions, policies, and socio-economic trends—impact land use changes in specific regions or landscapes. LCM is particularly important in understanding and managing ecological and environmental issues, urbanization, deforestation, agricultural expansion, and habitat fragmentation.
Reid's paradox of rapid plant migration 1970-01-01
Reid's paradox of rapid plant migration refers to a phenomenon observed in the study of plant ecology and biogeography. It is named after the British botanist David Reid, who noted that many plant species, particularly in temperate regions, have been able to rapidly expand their ranges far beyond what would be expected based on the rates of seed dispersal and the time it would take for plants to colonize new areas. The paradox arises particularly in the context of post-glacial plant recolonization.
Simulated growth of plants 1970-01-01
Simulated growth of plants refers to the use of computer models and simulations to mimic the biological processes and growth patterns of plants. This approach combines various scientific disciplines, including biology, ecology, geography, and computer science, to create digital representations of plants and their growth under different environmental conditions. ### Applications of Simulated Plant Growth: 1. **Research and Education**: Simulations can help researchers understand plant biology and growth dynamics without the logistics and time required for real-world experiments.
Climate and weather statistics 1970-01-01
Climate and weather statistics refer to data that describe the atmospheric conditions in a specific area over a certain period of time. Although the terms "climate" and "weather" are often used interchangeably, they represent different concepts: ### Weather - **Definition**: Weather refers to short-term atmospheric conditions in a specific place at a specific time. It includes elements such as temperature, humidity, precipitation, wind speed and direction, and atmospheric pressure.
Environmental statisticians 1970-01-01
Environmental statisticians are professionals who apply statistical methods and techniques to analyze data related to the environment. Their work focuses on collecting, analyzing, and interpreting data concerning environmental issues, such as pollution levels, climate change, natural resource management, and ecological changes. Key responsibilities of environmental statisticians may include: 1. **Data Collection:** Designing and implementing surveys and experiments to gather data on environmental variables, such as air quality, water quality, and biodiversity.
Line of greatest slope 1970-01-01
The "line of greatest slope" typically refers to a concept in the context of topography or geometry, where it indicates the steepest descent or ascent on a given surface. In the context of a graph or a mathematical function, it can refer to the line that represents the maximum rate of change of a function.
List of historical maps 1970-01-01
A list of historical maps refers to a compilation of maps that represent geographical regions, important historical events, or significant changes in territorial boundaries at various points in time. These maps can be valuable for understanding the social, political, and economic contexts of different eras.
Location 1970-01-01
Location refers to a specific point or area in physical space, defined by geographic coordinates, boundaries, or other identifying features. It can be described in various ways, depending on the context: 1. **Geographic Location**: This is often defined by coordinates, such as latitude and longitude. For example, the geographic location of the Eiffel Tower in Paris can be specified as approximately 48.8584° N, 2.2945° E.
MacChoro 1970-01-01
MacChoro is a Japanese music game application that combines elements of rhythm and puzzle gameplay. It encourages players to tap along to rhythm patterns, usually involving colorful visuals and catchy music. The game typically involves matching taps or swipes on the screen to the beat of the music. Players often have to navigate through increasingly complex levels, which can include various challenges and obstacles.
Map analysis 1970-01-01
Map analysis is a technique used to interpret and analyze spatial data represented in a map format. It involves examining the geographical relationships between different features, patterns, and variables depicted on the map, allowing for deeper insights into the data being represented. Here are some key aspects of map analysis: 1. **Spatial Relationships**: Analyzing the location and relationships of various geographical entities, such as cities, roads, rivers, and political boundaries. This includes understanding proximity, distribution, and connectivity.
Map layout 1970-01-01
A map layout refers to the arrangement and design of elements on a map, which helps to convey information effectively and clearly to the reader. The layout includes various components that are essential for understanding the depicted area and the data represented on the map. Key elements of a map layout typically include: 1. **Title**: A descriptive title that tells the user what the map represents.
Pollutant release inventories and registers 1970-01-01
Pollutant Release Inventories and Registers (PRIRs) refer to systems or databases that track and report the release of pollutants into the environment from various sources. These inventories are crucial for environmental protection and public health, as they provide valuable information about the types and quantities of pollutants being released, their sources, and their potential impacts on human health and the environment.

Epistemic possibility 1970-01-01
Epistemic possibility refers to the potential for a particular statement or proposition to be true, given what is known or believed at a certain point in time. It is concerned with the limits of our knowledge and what could be true based on the information we possess. In other words, if we say that something is epistemically possible, it means that, according to the available knowledge or evidence, there is at least a conceivable scenario in which that statement could be true.
Maximum elevation figure 1970-01-01
The Maximum Elevation Figure (MEF) is a term used in aviation to refer to the highest elevation, in feet or meters, of terrain, obstacles, or other features in a particular area, taking into account a specified vertical clearance. This figure is typically used in aviation charts, especially in the context of en route navigation and obstacle clearance. The MEF is important for pilots to ensure safe flight operations by providing information about the tallest structures and terrain in the vicinity.
